I understand that some people will not like this at all. It is annoying, you have a main character who's morally bankrupt, annoying and does not really seem to have any redemption value. Add to that decision making of the questionable kind and you have a dangerous mix. Dangerous because the interest of the viewer may wane to put it mildly.
Having said that and in stark contrast to all that, there are quite a few funny and really good moments. They may feel like skits and sometimes out of touch with the rest of the movie. And still they are able to elevate it, be it because of the humor, the tension or some sort short violence outburst. Sometimes a combination, which makes you wonder if underneath it all there was a way better movie, with a bit more time spent on the script, the characters and just in general. The main actress does her best to carry the movie (no pun intended), don't confuse despicable behavior with bad acting ... I hope this helped you decide if it is worth giving this a chance or not ...
